WHO: COVID-19 vaccine may completely degrade over time

Most of the opinions of some scientists and epidemiologists believe that booster vaccination is extremely necessary as well as the ability to vaccine against COVID-19 become an annual injection.

Ms. Soumya Swaminathan – Scientific Team Leader of the World Health Organization: “After contracting COVID-19, everyone will have an immune response. However, each person has a different immune response and it depends on whether you have a mild or severe COVID-19 infection Many studies now show that people with very mild or no symptoms of COVID-19 have very low levels of antibodies so here’s why We still recommend that even if you have been infected with COVID-19, you should continue to get vaccinated, as the vaccine then acts as an immune system booster.”

Ashish Jha – White House COVID-19 Response Coordinator: “The immune response to vaccination or to COVID-19 infection declines over time. This incorporates a virus that is becoming highly contagious. Rather, if we don’t have the resources to rebuild that immune wall with booster shots, with a new generation of vaccines, then I think the American people, as well as the people of other countries around the world, The world will remain vulnerable to the SARS-CoV-2 virus.”

Mr. Ugur Sahin – CEO of BioNTech pharmaceutical company: “We can now see that the SARS-CoV-2 virus is actually mutating faster, changing shape and self-replicating. Based on observations. I think there’s a good chance we need to get a shot of COVID-19 every year.”

Mr. Staphane Bancel – CEO of Moderna pharmacy: “I can see the world from 2023, where everyone aged 50 and over must get a booster shot against COVID-19 every year. Because they are the ones who are more likely to be hospitalized and die from COVID-19.”

Archana Chatterjee – Dean of Chicago Medical School at Rosalind Franklin University, USA: In order for the COVID-19 epidemic to stay under control, we will likely need some form of routine immunization, possibly an annual shot. or every 2 years or every 5 years. We need to collect more data to make a decision on this.”

Results from a study of more than 180,000 people by a group of Israeli scientists show that: Between 14 and 30 days after the fourth injection, COVID-19 infections decreased by 52%, hospitalizations decreased by 72%, and deaths decreased by 76%. compared with those who received three injections.

Another investigation found that people who received a second booster were still protected from serious illness 6 weeks after injection, with protection against breakthrough infection waning at week 8.
